Description

[Detailed explanation of the idea]

0001 The present invention relates to an automatic connection and separation device for two shafts in vehicle power lines, etc. .

0002

[Conventional technology]

3-4 illustrate conventional locking mechanisms. When the knob 22 is turned, the retainer 25, which has a helical gear cut on its outer periphery, moves into the retarder. move to the left while pressing the spring spring 26. As a result, driven gear 2 1 is pushed by the shift spring 24 and meshes with the drive gear 23, and the two shafts 1, 2 are concatenated. 3 shows a state in which the two shafts are separated, and FIG. 4 shows a state in which the two shafts are connected.

0003

[Problem that the idea aims to solve]

In the conventional example, all parts rotate together with one of the input and output shafts, so During the mobilization, it was difficult to supply power. Therefore, an inexpensive and reliable two-axis separation and connection mechanism has not been realized.

0004 The purpose of the present invention is to solve the problems of the conventional device, and to provide two devices that are inexpensive, small, and reliable in operation. To provide automatic shaft connection and separation equipment.

[0005]

[Means to solve the problem]

The two-shaft automatic connection and separation device of this invention has spline processing applied to the end of each shaft. The shafts 1 and 2 can be fitted to both the splines and can move along the splines. A sleeve 3 machined with an internal spline that can separate or connect both shafts, and the sleeve 3. a pressure supply means 9 for moving the sleeve and a means for changing the direction of movement of the sleeve; directional control valve 8, seals 5, 6, 7 for preventing leakage of the supply pressure, and the three It is characterized in that it has a guide 4 of 1.

[0006]

[Effect] [Shaft connection] The solenoid 12a is energized and the pressure from the pressure supply means 9 is introduced into the pressure chamber 11. , when sleeve 3 is moved to the right along the spline, the spline of sleeve 3 The splines fit into both the splines of the input shaft 1 and the output shaft 2, and the two shafts are connected. When the excitation of the solenoid 12a is stopped, the directional control valve 8 returns to neutral, and the pressure chamber 11 The pressure inside is maintained by the directional control valve 8, the seals 5, 6, 7 and the guide 4, The connected state of shafts 1 and 2 is maintained. [Shaft separation] Similarly, the solenoid 12b is energized to introduce pressure into the pressure chamber 10, and the sleeve 3 is When moved to the left, the connection between the two axes is released. Stop energizing solenoid 12b Then, the separated state of the two shafts is maintained as in the case of shaft connection.

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a state diagram in which the two shafts are separated, and FIG. 2 is a diagram in which they are connected. 1 is an input shaft, 2 is an output shaft, and male splines are attached to their opposing shaft ends. The inner cylinder of the sleeve 3 has a spline that can be fitted into the inner cylinder of the sleeve 3. The female spline is cut. In Figure 1, the splines of sleeve 3 fit into the splines of input shaft 1. , since it is not fitted with the spline of output shaft 2, the two shafts are in a separated state. . When the solenoid 12a of the directional control valve 8 is energized in this state, the pressure supply means 9 is activated. pressure is introduced into the left pressure chamber 11 of the sleeve 3, and the pressure causes the sleeve 3 to slides to the right along the spline and fits into the spline of the output shaft 2. figure 2 shows a state in which two shafts 1 and 2 are connected.

[0008] Further, when the excitation of the solenoid 12a is stopped from the above state, the directional control valve 8 becomes neutral. The state is restored, and the pressure introduced into the right pressure chamber 11 is transferred to the directional control valve 8 and the seal 5. , 6, 7 and the guide 4 to maintain the position of the sleeve 3. Next, when the solenoid 12b is energized in the opposite direction from the connected state, the pressure supply means 9 is activated. These pressures are introduced into the right pressure chamber 10 of the sleeve 3 and move the sleeve 3 to the left. Then, the two axes can be separated again.

[0009]

[Effect of the idea]

Since the present invention is constructed as described above, it is an inexpensive, small, and reliable automatic two-axis link. As a result, a separation device can be realized.
